Purpose The purpose of this paper is to provide the current state of knowledge about the Flash Crash. It has been one of the remarkable events of the decade and its causes are still a matter of debate. Design/methodology/approach This paper reviews the literature since the early days to most recent findings, and critically compares the most important hypotheses about the possible causes of the crisis. Findings Among the causes of the Flash Crash, the literature has propsed the following: a large selling program triggering the sales wave, small but not negligible delays suffered by the exchange computers, the micro-structure of the financial markets, the price fall leading to margin cover and forced sales, some types of feedback loops leading to downward price spiral, stop-loss orders coupled with scarce liquidity that triggered price reduction. On its turn leading to further stop-loss activation, the use of Intermarket Sweep Orders, that is, orders that sacrificed search for the best price to speed of execution, and dumb algorithms. Originality/value The results of the previous section are condensed in a set of policy implications and recommendations.

State Of Research

PurposeThe purpose of this paper is to provide a systematic review of articles on sport published in leading business studies journals within marketing, organisational studies and strategy.Design/methodology/approachBased on a review of 38 identified articles within the subfields of marketing, strategy and organisation studies published between 2000 and 2015, the articles’ topical, theoretical and methodological orientation within the studied subfields were analysed followed by a cross-subfield analysis.FindingsThe authors identify considerable differences in topical, theoretical and methodological orientation among the studied subfields’ associated articles. Overall, the authors also find that articles across all subfields tend to be focussed on contributing to mature theory, even though the subfield of marketing in particular exhibits contributions to nascent theory in contrast to organisation studies and strategy.Originality/valueThis paper contributes by illustrating the current state of research that is devoted or related to the phenomenon of sport within three subfields in business studies. Furthermore, the authors discuss the role played by leading business studies journalsvis-à-vissport sector-specific journals and offer avenues for future research.

Theoretical Side

Purpose Business Process Management (BPM) is key for successful organisational management. However, BPM techniques are often criticized for their inability to deal with continuous and significant change and uncertainty. Following recent calls to make BPM more agile and flexible towards change, this study presents the results of a systematic literature review (SLR) of agile concepts in BPM. Analysing and synthesising previous works and drawing on agility research in the field of IS, this paper introduces a framework for agile BPM. Integrating different components that define agility in the context of BPM, this framework offers a number of important implications. On the theoretical side, the authors argue that the concept of agile BPM departs in some important ways from traditional BPM research. This, in turn, points to various opportunities for future research. On the practical side, the authors suggest that emerging technologies, such as process mining, embody important features that help organisations to be more responsive to change. The paper aims to discuss these issues. Design/methodology/approach To assess the state of the art of agility in the BPM research, the authors conducted an SLR. More specifically, the authors drew on the approach of vom Brocke et al. (2009, 2015), which consists of five steps: defining the scope of the review; conceptualising the topic; searching for literature; analysing and synthesising literature; and developing a research agenda. Findings This study presents the results of a systematic review of agile concepts in BPM. This study then proposes a resulting research framework that can be used to strengthen the concept of agile BPM and provides an agenda for research in this rapidly growing and increasingly necessary area of BPM. Originality/value In this paper, the authors establish a shared understanding of agile BPM and develop an agile BPM framework that represents the current state as well as implications for research and practice in agile BPM.

Purpose The purpose of this paper is to discuss the current state-of-the-art in additive manufacturing, more commonly known as 3D printing, from the business perspectives. The primary drivers behind the development of the associated technologies are considered along with features that limit growth. Design/methodology/approach The approach is a personal perspective, based on approximately 25-years study of the development of the associated technologies and applications. Findings The discussion has found that the technology is still growing healthily, but with an understanding that there are numerous application areas that should be considered separately. Some areas are significantly more mature than others and success in some areas does not guarantee success in others. Originality/value This viewpoint has been prepared for the current state-of-the-art and can be compared with earlier viewpoints to see how things may have changed in the past. This should be of value to those interested to explore how the technology has developed in recent times and how it may move into the future.

Purpose Fog computing is a new field of research and has emerged as a complement to the cloud which can mitigate the problems inherent to the cloud computing model such as unreliable latency, bandwidth constraints, security and mobility. This paper aims to provide detailed survey in the field of fog computing covering the current state-of-the-art in fog computing. Design/methodology/approach Cloud was developed for IT and not for Internet of Things (IoT); as a result, cloud is unable to meet the computing, storage, control and networking demands of the IoT applications. Fog is a companion for the cloud and aims to extend the cloud capabilities to the edge of the network. Findings Lack of survey papers in the area of fog computing was an important motivational factor for writing this paper. This paper highlights the capabilities of the fog computing and where it fits in between IoT and cloud. This paper has also presented architecture of the fog computing model and its characteristics. Finally, the challenges in the field of fog computing have been discussed in detail which need to be overcome to realize its full potential. Originality/value This paper presents the current state-of-the-art in fog computing. Lack of such papers increases the importance of this paper. It also includes challenges and opportunities in the fog computing and various possible solutions to overcome those challenges.

Purpose – The purpose of this paper is to present an overview of the current state of debates surrounding Open Access (OA) in non-STEM disciplines. Design/methodology/approach – This paper uses a selective literature review and discussion methodology to give a representative summary of the state of the art. Findings – Non-STEM disciplines persistently lag behind scientific disciplines in their approach to OA, if the teleology towards open dissemination is accepted. This can be attributed to a variety of economic and cultural factors that centre on the problem of resource allocation with respect to quality. Originality/value – This paper will be of value to policymakers, funders, academics and publishers. The original aspect of the paper pertains to the identification of an anxiety of irrelevance in the humanities disciplines and a focus on “quality” in Open-Access publishing debates.
